ZX870H-3

World-Class Productivity - To yield high production yet maintain low fuel consumption, such was the objective of the development of a new engine and hydraulic system for the ZAXIS 850 / 850LC / 870H / 870LCH.

14 % more bucket digging force and 8 % more arm digging force.

(At power boost mode)

(vs. Conventional Model)

Enhanced Boom Recirculation System - In combined operation of boom lower and arm, arm speed can be increased by approximately 15 % over the conventional. Pressurized oil from boom cylinder bottom side is delivered to boom cylinder rod side to lower the boom, assisted by boom weight.

Conventionally, pressurized oil from pump is delivered to boom cylinder rod side to lower the boom. The new system also allows an efficient combined operation of swing and lowering the boom.

The new clean engine, complying with the emission regulations Tier 3 in US (EPA) and EU Stage III, can reduce fuel costs by electronic control.

Common Rail Type Fuel Injection System - Electronic control common rail type fuel injection system drives an integrated fuel pump at an ultrahigh pressure to distribute fuel to each injector per cylinder through a common rail.
